What’s behind the numbers?
Source: OneKey MLS, InfoSparks / MarketStats by ShowingTime and reconciled OneKey Matrix completed sales. Source checks: 2026-10-23 through 2026-10-23. Reporting month: September 2026. Single-family homes. Exact source geography: City/Town: Shelter Island.
Average means arithmetic mean; median is the middle completed-sale price. Days to an accepted offer use the source’s separate pending-data cohort, not time to closing. Inventory means active homes at month-end, not today’s listings. All prices, sizes, bedroom counts, years built and sale types are included within the stated property type. High and low are completed prices for this period and geography. A change in sales mix can change an average or median without the same change in every house. No home-specific appraisal or automated valuation is provided.
